Glioma is a type of brain tumor that originates from glial cells, which are supportive cells in the nervous system. These tumors can vary in their growth rate and severity, ranging from benign (non-cancerous) to malignant (cancerous). Common symptoms may include headaches, seizures, and changes in vision or personality, depending on the tumor's location in the brain. Treatment for glioma often involves a combination of surgery, radiation therapy, and chemotherapy. The specific approach depends on factors such as the tumor's grade and location. Ongoing research aims to improve outcomes for patients with gliomas, including studies on targeted therapies and immunotherapy.
